How Neodymium Magnets Work
What They Are Made Of
- They are made of rare-earth elements: Neodymium (Nd), Iron (Fe), and Boron (B).
- We make them using a special way called sintering. First we crush them up, and make them into magnet assemblies. Then the powder metallurgy process heats them up until they stick together.
- We make sure every magnet is perfect. Our manufacturing process has to meeting specific quality standards.
How Strong Are They?
Thing | What it Means | Why it Matters |
---|---|---|
N52 grade | The strongest kind of neodymium magnet you can buy. | Great for big jobs! |
Coercivity | How hard it is to make the magnet stop being a magnet. | Very important! |
Remanence | How much magnetic strength the magnet keeps. | Stronger is better! |
Curie temperature | When the tempeture is hot enough that the magnet longevity stops. | Don’t let it get too hot! |
Magnetization direction | Tells you with way the magnet pulls | Need to know for proper use. |
Magnetic field strength | How much power the magnet can produce | Determines magnet strength |
Flux density | Total magnetic field in specific areas | Determines magnet strength |
We test all our magnets to make sure they are super strong! We check the magnet strength testing
Types of Neodymium Magnets
Different Strengths (Grades)
- N35, N42, N52 are some of the magnet grades.
- Higher numbers mean a stronger magnet, bigger maximum energy product.
- Some need high-temperature stability, use N42SH!
Different Coats
- Magnets can get rusty, so we can coat them.
- Nickel, epoxy, and zinc are common.
- Nickel plating A nickel-copper-nickel coating is the best!
All Shapes and Sizes
- We make discs, blocks, rings, and more!
- Need a custom neodymium magnets? We can do that! We have lots of magnet dimensions.
What are, Where used? Top Applications
Big Jobs (Industrial Uses)
- Wind turbines use big, strong magnets. Big motor magnets are used in industrial lifting magnets
- Electric motors use magnets to spin.
- Magnetic separators remove metal bits from other stuff.
- They can be used in eddy current separators, and magnetic couplings.
Stuff You Use Every Day
- Consumer electronics
- Headphones in speaker drivers use small magnets to make sound.
- Hard disk drives (HDDs) use magnets to store your pictures.
- Magnetic resonance imaging (MRI) use the stongest type of magnets.
Why NdFeB Magnets Are Great
- They are super strong for their size!
- You don’t need a giant magnet to do a big job.
- We can make them just how you need them!
Be Careful! Magnet Safety Hazards
- Neodymium magnets are brittle. They can break, crack, or chip.
- We coat our magnets to help them last. Magnet corrosion prevention is critical.
- Don’t let them get too hot! That can harm the demagnetization resistance.
- We have magnet saftey guidelines and do magnet saftey training to make working with permanent magnets safe.
How to Pick the Right MagnetRecyclable magnets
5 Important Things
- Grade: How strong do you need it? N30, N35, N42?
